To train a "Custom Template" model (not neural), what is the minimum number of document samples required?
check_circle
Correct AnswerD
For template-based custom models (fixed layout), a minimum of 5 samples is required to start training.
Question 252
You want an agent to act as a "Technical Lead" and follow a specific checklist for every response. Where should this be defined?
check_circle
Correct AnswerB
System Instructions (or the System Prompt) define the persona, rules, and persistent constraints for the agent.
Question 253
You are building an agent that needs to analyze a 30-second video clip to detect a safety violation on a construction site. Which model is best?
check_circle
Correct AnswerB
GPT-4o's vision capabilities allow it to process video frames and reason about temporal events and visual safety protocols.
Question 254
Which "Security Center" feature provides a "Secure Score" and recommendations for your AI infrastructure?
check_circle
Correct AnswerC
Defender for Cloud monitors your AI resources for misconfigurations (like public access) and provides hardening steps.
Question 255
Which multimodal model parameter controls how many tokens are allocated to "looking" at an image?
check_circle
Correct AnswerB
The detail setting determines if the model uses a low-res (65 tokens) or high-res (multi-crop) version of the image.
Question 256
You want to export enriched data from your search pipeline to Power BI for a dashboard. Which feature should you configure in the Skillset?
check_circle
Correct AnswerB
Knowledge Store Projections allow you to save enriched data into Azure Tables or Blobs, which Power BI can easily ingest.
Question 257
You are using "Chain-of-Thought" (CoT) prompting. Why is this beneficial for complex reasoning?
check_circle
Correct AnswerD
Breaking a problem down into steps allows the model's internal attention mechanism to focus on individual logic components.
Question 258
Which Azure RBAC role is required for a developer to query an index but not modify the index schema or delete data?
check_circle
Correct AnswerD
This specific "Data Plane" role grants permission to read/query index content without administrative rights over the resource itself.
Question 259
You want to reduce the "Token Costs" of a high-volume support bot. What is the first optimization to try?
check_circle
Correct AnswerC
Using a tiered approach—where a small model handles easy tasks and a large model handles hard ones—is the best cost-saver.
Question 260
You need to give an AI Agent the ability to create and manage its own Threads and Runs in a specific project. Which role should you assign to its Managed Identity?
check_circle
Correct AnswerD
The "OpenAI Contributor" role provides the necessary permissions to manage the full lifecycle of agentic resources like Threads, Runs, and Assistants.
